THOMAS ROBINSON, OF MINNEAPOLIS, MINNESOTA.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 442,788, dated December 16, 1890.

Application filed April 19, 1890. Serial No. 348,615. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS ROBINSON, of

Minneapolis, in the county of Hennepin and.

State of Minnesota, have invented a new and Improved Window-Screen, of which the following is a full, clear, and exact description.

My invention relates to improvements in removable window-screens and the invention consists in the particular construction and arrangement of parts, as hereinafter fully de scribed, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective inside view of a window and window-frame with the screen embodying my invention secured in the window-frame. Fig. 2 is a detailed perspective View of the window-screen, the same being in a partially-open position; and Fig. 3 is a detailed perspective view of the locking-plates and bolt.

I have shown a window-frame A, provided with two window-sashes B and B, which move vertically in the window-frame between the strips a thereof, in the usual manner.

The window-screen is composed of two similar frames 0, the width of the open united frames corresponding to the width of the window and the height of the frame corresponding to the distance between the bottom of the upper sash B and the window-sill, so that when the screen is in position in the window the upper part of the frame will abut with the lower portion of the sash B. The inner edges of the frames 0 are rabbeted, thus forming vertical shoulders b, which will interlock when the screen is opened, and the frames 0 are hinged together at their inner edges by the hingesd.

Fixed to the central abutting stiles O of the frames 0 are metal plates D, having vertical slots D therein, the plates D being fixed to the inner edges of the stiles-that is, to the parts next the central web of the screenframes, so that said plates will be in horizontal alignment.

The stiles O are provided with horizontal bores opposite the slots of the plate D, as indicated by dotted lines in Fig. 2, so that when the frames 0 are opened the bolt E may be inserted through the slots D and through the stiles O. The bolt E is provided at each end with a semicircular flattened head E, and the length of the bolt corresponds to the thickness of the two stiles C, so that when the frames O are opened the bolt E may be inserted through the plates D and through the stiles O, with the bolt-heads E in a vertical position, and the boltheads may then be turned into a horizontal position, thus overlapping the edges of the slot D and securely fastening the frames O in open position.

The frames O are provided with the ordinary screen-cloth, and fixed to the inner sides of the frames are suitable handles f, by which the frames may be pulled into open position. To insert the screen in a window, the lower sash B is raised, and the screen, with the frames O in a partially-open position, as shown in Fig. 2, is placed beneath the upper sash B in the window-frame A, and with the outer edges of the frames 0 abutting with the inner portions of the window-frame. Then by taking hold of the handles f and pulling inwardly the central portion of the frames 0 will be closed tightly together, in which position they may be locked by the bolt E, as described above.

It will be seen that the screen will be entirely outside of the lower sash, so that the same may be raised and lowered without interfering with the screen.

I have shown my invention as fixed in the lower portion of a window, in which position it is usually used; but it is obvious that it may be applied to the upper part of the window as well.

In the foregoing description it will be seen that when the two frames O are locked to getherin the manner described they will be nearly as solid and substantial as a single frame, and that when taken from the window they may be folded together to be stored, and will occupy but little space.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with two frames having their inner edges rabbeted and hinged together at the said inner edges, said abutfixed to the stiles O and provided with ver-,

tical slots D, aligning with the bores of the stiles C, a bolt E, adapted to pass through the stiles and slotted plates, said bolt having flattened heads E, and suitable handles f for operating the screen, substantially as shown and described.

THOMAS ROBINSON.
